If you're looking for the biggest schnitzel sandwiches that you've had in your life, you've found 'em. I had the chicken schnitzel for lunch and I couldn't even finish it. It was extremely good though.
The sandwiches are made on a freshly baked bun and all of the schnitzel's (wiener, chicken or pork) have their homemade tomato sauce and either medium or hot peppers. They also serve a great beef sandwich, a "Blue Danube" (pork, ham, cheese) and a fried eggplant sandwich.
At only $6.95 each (with a ton of toppings included), it's well worth it.
